Using the addition rule of the Sine function and the Cosine function, we obtain .
<h3>What are the formulas for (sin x + sin y) and (cos x + cos y)?</h3>
- The formula for the addition of two Sine functions () is .
- The formula for the addition of two Cosine functions () is .
Given that
Then using the above formulas, we get:
(1)
(2)
Dividing the equation (1) by (2), we get:
(3)
Now, we know that .
Thus, using the above formula, we get from (3):
Therefore, using the addition rule of the Sine function and the Cosine function, we obtain .

Even chance/possibly with all the other colors
because there is 5 of each colour making it not so likely to pull one color more then the other but less likely of not pulling that color at all
hope this helps
3 1/5 x 7 1/4
= (15/5 + 1/5) x (28/4 + 1/4)
= 16/5 x 29/4
= (29x16) / (5x4)
= 464/20
= 116/5
= 20 16/5
